Chromatography Research Supplies (CRS) Conflict Minerals Policy

The U.S. Securities and Exchange Commission (SEC) instituted rules as mandated by the Dobb-Frank Act on August 22, 2012. The law requires U.S. and foreign companies to report annually and makes public the use of "conflict minerals" from the Democratic Republic of the Congo (DRC) and its adjoining countries. The 9 adjoining countries are: Rwanda, Burundi, Tanzania, Congo Republic (a different nation than DRC), Angola, Sudan, Central African Republic, Zambia and Uganda.

CRS supports worldwide concerns that Gold, Tin, Tungsten and Tantalum mined from the conflict areas of the Democratic Republic of the Congo (DRC) may be making their way into the supply chain. We are committed to supporting our customers' requirements with reference to the Conflict Mineral Law.

CRS's suppliers are expected to have in place policies and due diligence measures that will enable us to reasonably assure that products and components supplied to use containing conflict minerals are DRC conflict free. CRS asks all its suppliers to submit a completed EICC-GeSI public Conflict Minerals Reporting Template.
